Reading your lineage of the Post family and the Pane-Joyce Genealogy for the same family I find the abbreviations "ym" and "yd" that do not seem to mean "year married" or "year died". What do these mean? I am new to finding my family's history and haven't found where these abbreviations are defined. Thank you for taking the time to help this "newbie".
Virginia - Excellent question. I neglected to give a link to where these Dutch church abbreviations are explained.
Please see Translations of Words in Dutch Church Records for y.m, y.d and other commonly used abbreviations
